Tensioning devices, specifically designed for overhead line equipment (OLE) systems in railways, are specialised tools or equipment used to apply and adjust tension in the contact wires or other OLE components.
These devices ensure proper tensioning of the OLE system, which is crucial for maintaining the desired height, alignment, and electrical performance.
Here’s an overview of OLE tensioning devices:
Tensioning Drums: Tensioning drums are used to apply tension to the contact wires or other OLE conductors. They are typically mounted on tensioning vehicles or gantries and utilize mechanical or hydraulic mechanisms to adjust the tension. Tensioning drums ensure consistent tension across the OLE system, promoting stable and reliable performance.
Tensioning Machines: Tensioning machines are specialized devices used for applying and adjusting tension in OLE wires or conductors. They often feature hydraulic or pneumatic systems that allow precise control of the tensioning force. Tensioning machines are portable and can be easily moved along the tracks to perform tensioning operations.
Tensioning Gauges: Tensioning gauges are tools used to measure and monitor the tension in the OLE wires or conductors. These gauges provide accurate tension readings, allowing maintenance personnel to ensure the proper tension levels are maintained within the desired range.
Tensioning Grips: Tensioning grips are devices used to secure and grip the OLE wires or conductors during tensioning operations. They provide a reliable grip, allowing for controlled tensioning without damaging the wires. Tensioning grips come in various designs to accommodate different wire sizes and configurations.
Proper tensioning of the OLE system is essential for maintaining the required clearances, wire height, and electrical contact. It ensures optimal performance, reduces wear and tear, and prevents sagging or excessive vibration of the contact wires.
